Dynamic location search suggestions based on travel itineraries

ABSTRACT

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for retrieving local information on a user device include detecting itinerary information stored by a first application on a user device, and identifying a travel destination based on the detected itinerary information. The travel destination is communicated to a second application executable on a user device, and the travel destination is stored in association with the second application. The second application is adapted to retrieve local information based on an identified geographic location, and local information for the travel destination is provided through the second application in response to a user interaction with the second application and based on a triggering threshold associated with the itinerary information.

BACKGROUND

This specification relates to providing dynamic city search suggestionsbased on travel itineraries, including suggesting locations to search inone application based on travel plans identified in a differentapplication.

Smart phones provide access to numerous sources of data and can runapplications that organize and allow searching of information forspecific topics. For example, weather applications may allow users tosearch for and/or select locations (e.g., cities) and to store theselected locations for use in retrieving information about local weatherconditions, forecasts, radar, etc. The location data can be persisted inthe application such that each time the application is opened, the localinformation can be updated for each of the stored locations. Other typesof applications can perform similar operations to, for example, retrieveother types of local information for one or more selected locations eachtime an application is opened or activated from a background orhibernation state. In addition to allowing users to search forlocations, some applications may allow the use of a current location, asdetected through a global positioning satellite device or otherpositioning technique.

SUMMARY

In general, itinerary information received or detected on a user devicein one application (e.g., a travel application) can be used toautomatically and dynamically update persistent location data in one ormore other applications (e.g., weather, clock, or dining applications).A destination location can be extracted from the itinerary informationand provided to the one or more other applications, which can use thereceived application to automatically retrieve local information for thedestination location. The timing of when the other applications retrievethe local information can be determined based on user preferences,defaults, travel dates, type of application, and/or other parameters.The other applications can execute on the same user device or on adifferent user device. For example, based on an itinerary stored in atravel application on a user device, destination information can beprovided to a weather application and a clock application on the sameuser device, in addition to being provided to a weather application anda clock application on a friend's user device. The weather and clockapplications can automatically search for weather and time informationfor the destination, although the timing of when such searches areperformed can be delayed until closer to the travel date. Once the tripis complete, the destination can be removed from being persisted in theweather and clock applications, although the timing and performance ofthe removal can depend on user preferences, defaults, future travelinformation, type of application, and/or other parameters.

In one general aspect, a method of providing information in oneapplication based on travel plans includes detecting itineraryinformation stored by a first application on a user device; identifying,by operation of a computing device, a travel destination based on thedetected itinerary information; communicating the travel destination toa second application executable on a user device; storing the traveldestination in association with the second application, wherein thesecond application is adapted to retrieve local information based on anidentified geographic location; and providing local information for thetravel destination through the second application in response to a userinteraction with the second application and based on a triggeringthreshold associated with the itinerary information.

DETAILED DESCRIPTION

When people travel to new locations, they often desire to obtaininformation about the location. For example, two common topics ofinterest are the weather and the time at the destination location. Othertopics may also be relevant, including local dining and transportationoptions, events and activities, or other local information. Travelerscan search for such information through web browsing, for example,before leaving on a trip, and smart phones and other handheld orportable user devices can often be used to search for such informationbefore and during travel. A user may access multiple applications orretrieve multiple web pages to obtain the information of interest.Unless the user has previously stored the location in an applicationthat can provide local information for various locations, however, theuser typically has to perform a search and/or otherwise manually add thedestination location to the application. In accordance with techniquesdescribed in this specification, travel information entered and/orstored in one application on a user device can be leveraged to providelocation suggestions or to automatically retrieve local information fora travel destination in one or more other applications. For example,local information for a travel destination can be retrieved in otherapplications on the user device without having to manually enter thelocation or search for the location. In addition, local information canbe provided to applications on other user devices (e.g., devices offriends or relatives authorized to receive such information) so thatother users also have access to local information where a friend orrelative is visiting or otherwise currently located.

FIG. 1 depicts a schematic representation of a system 100 for sharingdestination information among different applications on a user device.In general, the system 100 includes one or more source applications 102that can be used to access or store itinerary information. For example,the source applications 102 can include a travel application 102(1) thatmay be used to create, store, or organize travel plans (e.g., flightnumbers and schedules, hotel reservations, and rental car reservations),a calendar application 102(2) that can store future appointments ortravel plans, and a social media application 102(3) that can storeinformation about events (e.g., events for which the user has acceptedan invitation). Other types of source applications 102 can also be used.In general, a source application can provide location information forsome future event that may be of interest to the user. The sourceapplications 102 execute on an operating system 104 that provides anexecution environment, which can provide services and basicfunctionality. One or more target applications 106 also execute on theoperating system 104 and are programmed to retrieve and provide localinformation through a user interface of the user device. In particular,the target applications 106 can retrieve and provide local informationfor locations identified based on itinerary information stored in one ormore of the source applications 102. The target applications 106, caninclude, for example, a weather application 106(1) that can retrievecurrent weather conditions and forecasts, a clock application 106(2)that can retrieve current local time at specific locations, a diningapplication 106(3) that can retrieve restaurant information and/orfacilitate reservations, and a mapping application 106(4) that canretrieve local map information.

The travel application 102(1) can store itinerary information 108(1),108(2) that identifies one or more destinations (e.g., Destinations A,B, and C). The itinerary information 108(1), 108(2) can also includetravel dates and times. The itinerary information 108(1), 108(2) can bemanually entered into the travel application 102(1) or automaticallyretrieved or stored by the travel application 102(1) in response to theuser booking travel plans. For example, a user may purchase airlinetickets through the travel application 102(1), which may store theairline itinerary information. Alternatively, the travel application102(1) may be associated with a user account that has itineraryinformation stored in association with the account. The itineraryinformation 108(1), 108(2) can be automatically synchronizedperiodically with the user account. As another alternative, the travelapplication 102(1) may interface with other applications on a userdevice to receive the itinerary information 108(1), 108(2). The calendarapplication 102(2) may also be used to store appointments 110, which caninclude date and location information (e.g., location D). The socialmedia application 102(3) can similarly store events 112, which caninclude data and location information (e.g., location E).

Each of the source applications 102 can include an applicationprogramming interface (API) 114 through which data (e.g., location,date, and time) from the source application 102 can be provided to theoperating system 104 or to other applications, such as targetapplications 106. The API 114 can operate to automatically forward thedata or to allow retrieval of the data in response to a request from theoperating system 104 or a target application 106. In someimplementations, the operating system 104 can include a destinationupdate module 116 that can interface with the API 114 to receive datafrom the respective source application 102. The destination updatemodule 116 can operate to store the data received from the sourceapplications 102 for subsequent forwarding to or retrieval by the targetapplications 106. For example, the destination update module 116 canstore the data until a target application 106 is activated (e.g., openedor taken out of an idle state), until the target application 106requests the data, and/or until a predetermined triggering threshold(e.g., time, date, and/or user device location) occurs.

The target applications 106 generally include applications that arecapable of retrieving local information. Typically, the targetapplications 106 can provide local information in response touser-specified search parameters entered through a corresponding searchuser interface (UI) 118(1), 118(2), 118(3), 118(4) for the respectivetarget application 106. The target applications 106 can also providelocal information for locations retrieved or otherwise provided by thesource applications 102. For example, the weather application 106(1) canprovide local weather conditions and forecasts for each of DestinationsA and B 120, 122 and Locations D and E 124, 126 based on data receivedfrom the source applications 102. In addition, the weather application106(1) can provide local weather conditions and forecasts for otherlocations (e.g., Location X 128) identified through search UI 118(1).The clock application 106(2) can provide local time for each ofDestinations A and B 130, 132 and Locations D and E 134, 136 based ondata received from the source applications 102. In addition, the clockapplication 106(2) can provide local time for other locations (e.g.,Location Y 138) identified through search UI 118(2). Similarly, thedining application 106(3) can provide local dining options or otherinformation, and the mapping application 106(4) can provide local maps,for each of Destinations A and B 140, 142, 150, 152 and Locations D andE 144, 146, 154, 156 based on data received from the source applications102. In addition, the dining application 106(3) and the mappingapplication 106(4) can provide dining information and local maps forother locations (e.g., Location Z 148, 158) identified through acorresponding search UI 118(3), 118(4). Although not depicted in FIG. 1,each of the target applications 106 can include an API for interfacingwith the source applications 102 and/or the operating system 104 andreceiving data originating from the source applications 102.

In some implementations, the target applications 106 do not providelocal information until some triggering threshold occurs. For example,the local information may not be provided until shortly before a trip isscheduled to begin. Different target applications can provide the localinformation beginning on different dates even for the same location. Forexample, the weather application 106(1) may begin displaying localweather conditions and forecasts for Destination A 120 a week beforetravel is scheduled, while the clock application 106(2) may begindisplaying local time for Destination A 130 the day travel is scheduled.Triggering thresholds can also be used to determine when to remove orstop displaying local information. Triggering thresholds for adding andremoving local data can depend on the dates and times associated withitinerary information, type of application, frequency of travel to thelocation, length of the trip, detected current location of the userdevice, and/or other criteria.

FIG. 2 is a block diagram of a computing device 200 that can be used toimplement the system 100 of FIG. 1. The computing device 200 includes aprocessor 202, a memory 204, a user interface 206, and a locating device208. Applications within an application set 220 stored in the memory 204can execute in an execution environment 212 of operating system 210. Theapplications can interface with other applications in the applicationset 220 and/or with the operating system 210 through APIs 214 that maybe included in the applications 220 and/or as part of the operatingsystem 210. Any number of individual applications 222, 224, 226 can bestored in the memory 204 for execution. Each individual application 222,224, 226 can includes application instructions 228, 232 and applicationdata 230, 234. The application instructions 228, 232, when executed inthe execution environment 212 provide the application functionality. Forexample, a first application 222 can include application instructions228 that allow a user to define a travel itinerary, for example,directly through a user interface input 242 (e.g., manually typing indestination and travel date information) or through a reservation systemcapable of interacting with the first application 222 (e.g., the travelitinerary can be reserved through the first application or the travelitinerary can be synchronized with user account information stored on aremote server). The travel itinerary can be stored as a portion of theapplication data 230. The application instructions 228 can also includeinstructions that cause the application to forward or otherwise provideitinerary information, including information identifying traveldestinations to the operating system or to other applications. Forexample, the application instructions 228 can include instructions thatprovide itinerary information through an API 214.

Another application 226 can include application instructions 232 thatare used to provide access to weather information for selectedlocations. For example, the application instructions 232 can retrieveweather information for locations that a user has manually typed in orsearched for through the user interface input 242. The applicationinstructions 232 can also retrieve weather information for locationsidentified based on data (e.g., destination) received from the firstapplication 222 (e.g., through APIs 214). The identified locations canbe stored in the application data 234. The weather information foridentified locations can be retrieved through a network 260 (e.g.,Internet) from an application server 270 and provided to a user of theuser device 200 through a user interface display 240. In someimplementations, sharing of the location information can be based onuser preferences or authorizations, which can be defined through theindividual applications 222, 226 and/or through the operating system210. In some cases, and as further discussed below, operations performedby the applications 222, 224, 226 can be based in part on a currentlocation of the user device 200 as detected by a locating device 250(e.g., a satellite-based or terrestrial-based locating system, such asGPS or cellular triangulation). Among other things, addition or removalof locations in the application data 234 can be based, at least in part,on the current location of the user device 200.

FIG. 3 is a schematic diagram of an example system 300 for sharingdestination information between applications on different user devices302, 304. Itinerary or travel destination information from a travelapplication 310 or other application on a first user device 302 can beshared with a weather application 320 or other application on a seconduser device 304. For example, a user of the second user device 304 canobtain local information for the location of a user of a first userdevice 302. Such a feature may allow a user to provide, for example, aspouse or close relative with information about the current weatherconditions or current time where the user is traveling. To facilitatesuch sharing of information, the travel application 310 may include abuilt-in or add-on API 312 that forwards location information and/orother itinerary information to a weather application 320 on the seconduser device 304. The location information can be provided to the weatherapplication 320 through an API 322. The weather application 320 caninclude instructions that cause the application to automaticallyretrieve weather information for the received location (or suggest thereceived location as a weather location of interest).

In some implementations, the travel application 310 may include abuilt-in or add-on API 312 that forwards itinerary information to, orallows retrieval of itinerary information by, a sharing application 314on the user device 302. The sharing application 314 can be built intothe operating system of the user device 302 or included as a separateapplication that executes on the user device. The sharing application314 can interact with a corresponding sharing application 324 on thesecond user device 304 to share itinerary information. The sharingapplication 324 on the second user device 304 can provide the itineraryinformation received from the first user device 302 to the weatherapplication 320 through the API 312. In some implementations, sharing ofthe itinerary information can be facilitated by a sharing applicationserver 330, which can interface, for example, with sharing applications314, 324, or directly with the travel application 310 and/or the weatherapplication 320. For example, sharing application 314 or travelapplication 310 can forward itinerary information to sharing applicationserver 330, which can store the itinerary information in a destinationdatabase 332.

The sharing application server 330 can, in addition or as analternative, control whether information is shared between particularuser devices (e.g., whether information from the user device 302 isshared with the second user device 304). Accordingly, the sharingapplication server 330 can determine whether the itinerary informationis provided to the second user device 304 according to permissions,subscriptions, or other data stored in a friend database 334. Forexample, a user of the first user device 302 can define other users thatare permitted to receive itinerary data from the travel application 310,the sharing application 314, and/or other applications on the userdevice 302. These permissions can be added manually, in response to asuggestion (e.g., a suggestion made by software based on frequentinteractions with a user of the second user device 304), orautomatically based on permissions granted in other applications or inthe operating system of the first user device 302. Similarly, the userof the second user device 304 can subscribe to information from otherusers (e.g., the user of the first user device 302) manually,automatically, or in response to a suggestion. By subscribing to suchinformation, the second user device 304 can automatically receiveitinerary information from the first user device 302. The user of thesecond user device 304 can also subscribe to or receive individualevents or itineraries. In some implementations, the described functionsof the sharing application server 330, the destination database 332,and/or the friend database 334 can be built into software and the userdevices 302, 304, e.g., in the sharing application 314, 324.

Although FIGS. 2 and 3 present specific examples of a travel applicationand a weather application, other types of applications can also be used.As with the different applications described above in connection withFIGS. 1 and 2, the different applications 310, 320 can be distinguishedby the performance of different functions, operation on differentinputs, and display of different user interfaces. For example, therespective application instructions can present different types ofinformation to users, such that the applications are not merelydifferent instances or versions of the same application.

FIG. 4 depicts a mobile device 400 displaying a travel applicationinterface 402. The travel application interface 402 includes itineraryinformation for three different trips, including a trip 404 to Seattlescheduled for December 11-14, a trip 406 to Chicago scheduled forFebruary 8-12, and a trip 408 to Seattle scheduled for March 22-23. Thetravel application can also store additional information associated witheach itinerary. In general, the itinerary information can be enteredthrough appropriate interfaces in the travel application, can bereceived from a server (e.g., associated with the travel application orwith one or more user travel-related accounts), or can be synchronizedwith travel information stored in other applications on the user device.In some implementations, the travel application can include informationthat is updated dynamically. For example, the travel application maystore flight arrival and departure times that are updated automaticallyfrom a server when the flight times change and the travel applicationmay be programmed to automatically update to reflect user-initiatedtravel changes such as date of travel by synchronizing with anotherapplication on the user device 400 or with changes stored on a remoteserver. The travel application interface 402 includes an icon 410 thatallows a user to add new travel itineraries.

FIG. 5 depicts the mobile device 400 of FIG. 4 displaying a weatherapplication interface 502. The weather application interface 502 can bedisplayed, for example, in response to a user closing (or exitingwithout closing) the travel application of FIG. 4 and opening a weatherapplication. The weather application can provide the user with weatherfor one or more selected cities or other locations. As depicted in thisexample, the weather application interface 502 displays current weatherand the current day's forecast information 504 for Phoenix. Otherinformation can also or alternatively be presented, including, forexample, other current condition information (e.g., wind speed anddirection) or forecast information by the hour or for the next few days.In general, other cities or locations can be added to the weatherapplication by selecting an icon 510 that can allow a user of the userdevice 400 to search for or manually select other locations. Based oninformation from the travel application of FIG. 4, however, the weatherapplication can cause the weather application interface 502 to display apop-up window 512 that suggests (and requests authorization to add)another location. In this example, the inclusion of a travel itinerarythat includes Seattle in the travel application can cause the weatherapplication interface 502 to display a pop-up window 512 that requestsauthorization to add Seattle as a location that is persisted in thememory associated with the weather application. The pop-up window 512can be presented the next time the weather application is opened afterSeattle is added as a travel destination, or at some later time (e.g., afew days before the trip to Seattle is scheduled to begin). As describedabove, the suggestion of Seattle within the weather application can bebased on information communicated to the weather application through oneor more APIs included in the travel application, the weatherapplication, or the underlying operating system on which theapplications execute.

FIG. 6 depicts the mobile device 400 of FIG. 4 displaying an updatedview of the weather application interface 502. In the updated view, theweather application interface is updated to include weather conditionsand forecast information 606 for Seattle in addition to weatherconditions and forecast information 608 for Dallas. The Seattleinformation 606 can be added as a result of accepting the suggestion inthe pop-up window 512 of FIG. 5 or automatically adding the informationbased on travel itinerary information from the travel application ofFIG. 4.

FIG. 7 depicts the mobile device 400 of FIG. 4 displaying an invitationto share travel itinerary information with another user. In particular,in response to adding itinerary information to the travel application(or in response to some other trigger), the travel application can causethe travel application interface 402 to display a pop-up window 712 thatsuggests (and requests authorization to) share information from theSeattle travel itinerary with a second user. For example, theinformation can be shared with a different application (e.g., a clock orweather application) on a user device of the second user. The seconduser can be suggested based on stored “friend” information, based onprior (e.g., frequent) interactions with the second user, or othercriteria.

FIG. 8 depicts the mobile device 400 of FIG. 4 displaying an alternativeuser interface of the weather application interface 502. In particular,in response to a user selection of the icon 510 of FIG. 5, the weatherapplication interface 502 can be updated to include an interface formanually searching for locations by typing search parameters into asearch field 812 using a character key 814. Other techniques formanually identifying locations to add to an application can also be used(e.g., selecting from a list).

FIG. 9 depicts the mobile device 400 of FIG. 4 displaying an alternativeuser interface of the weather application interface 502. Based oninformation from the travel application of FIG. 4, for example, theweather application can cause the weather application interface 502 todisplay a pop-up window 912 that requests instructions on whether toremove a location from the location list associated with theapplication. For example, the pop-up window 912 can be displayed as aresult of detecting that end date and/or time of a travel itinerary hasoccurred. Alternatively, in some implementations, a location can beautomatically removed without requesting confirmation from a user. Inaddition, in some situations, a location may be automatically retainedas a result of determining that the location is a frequent destination.Although the example of a weather application is used throughout FIGS.4-9, other types of applications that retrieve information based onlocation can be used.

FIG. 10 is a flow diagram of a process 1000 for automatically providinglocal information in one application based on itinerary information inanother application. Itinerary information is received on a user device(at 1002). The information can be received through a travel reservationmade through the user device or through a user account that synchronizeswith the user device or the information can be manually added by a user.The received itinerary information is stored by a first application onthe user device (at 1004). The first application include, for example, acalendar, an application that stores travel or event informationreceived from a server or another application on the same user device, asocial media application, or a mapping application. A travel destinationis identified based on the detected itinerary information (at 1006). Oneor more target applications for sharing the destination data areidentified (at 1008). The target applications can be identified based onparameters or user preferences associated with the first application orwith the operating system of the user device. The target applicationscan be stored on the user device or can be associated with a differentuser device. A confirmation that sharing is authorized can be made (at1010). For example, the first application, the operating systemassociated with the user device or another user device, a server thatstores authorization information, and/or the second application candetermine whether a user has authorized sharing of the information withthe second application.

The travel destination is communicated to the second application andstored in association with the second application (at 1012). In somecases, the travel destination can be stored for some period in anintermediate location (e.g., by the user device operating system). Atriggering threshold is identified for retrieving local information forthe travel destination using the second application (at 1014). Aninitiation triggering threshold can be based, for example, on a traveldate and/or may be dependent upon when and how often a user opens theapplication. Moreover, the triggering threshold can be determined by thesecond application, by an operating system that provides the traveldestination to the second application, or by a server that stores thetravel destination during some interim period. The triggering thresholdcan also include parameters defining when and if the travel destinationand/or the local information should be removed from the secondapplication. Based on the initiation triggering threshold, the secondapplication retrieves local information for the identified traveldestination (at 1016), and the local information for the traveldestination is provided through the second application (at 1018). Forexample, the local information can be displayed in response to a userinteraction with the second application (e.g., opening the applicationand/or accepting a suggestion to retrieve the local information for thetravel destination). The local information (or the travel destination)is removed from the second application (or from being associated withthe second application) based on a removal triggering threshold (at1020). For example, the removal triggering threshold can be associatedwith timing of the end of a trip or other event.

FIG. 11 is a representative timeline diagram of a process 1100 forautomatically providing local information in an application-basedinformation from another application. The process 1100 occurs along atimeline 1102. A travel itinerary is received and one or moredestinations are identified (at 1104). The destinations are stored foruse in one or more target applications (at 1106). For example, thedestinations can be stored in the target applications or for laterdelivery to the target applications in accordance with triggeringinformation. Local information (e.g., weather or dining options) for afirst destination A is retrieved in a first target application (at1108). The retrieval of the local information for destination A in thefirst target application can be triggered a predetermined period of time1110 prior to a date of travel 1112 to destination A. For example,retrieval of weather information may be triggered four or five daysbefore the travel date 1112. Local information (e.g., time) for thefirst destination A is retrieved in a second target application (at1114). The retrieval of the local information for destination A in thesecond target application can be triggered a predetermined period oftime 1116 prior to a date of travel 1112 to destination A. For example,retrieval of time information may be triggered one day before the traveldate 1112. Thus, triggers (including both initiation or retrievaltriggers and removal or deletion triggers) can be different fordifferent target applications. In some implementations, the triggers canbe determined based on default or user-defined triggering parameters andcan also include receiving a user confirmation that a destination shouldbe added or removed. The triggers can also define when the destinationinformation is provided to the target application and/or when the targetapplication begins retrieving local information for the destination. Insome implementations, the triggers can be based on other informationbesides time, including location of the user device (e.g., arrival atthe airport for outgoing or return travel) or other information.

If the itinerary includes multiple destinations, local information for asecond destination B is retrieved in the first target application (at1118) a predetermined period of time 1120 prior to a date of travel 1122to destination B, and local information for the second destination B isretrieved in the second target application (at 1124) a predeterminedperiod of time 1126 prior to the date of travel 1122 to destination B.Local information in the target applications for the first destination Acan be deleted and/or the persistence of the destination in memory canbe removed from the target applications (at 1128) when travel to thesecond destination begins or is scheduled to begin or based on someother removal trigger. Similarly, local information in the targetapplications for the second destination B can be deleted and/or thepersistence of the destination in memory can be removed from the targetapplications (at 1130) when a stay at the second destination B iscomplete.
